In the process of trying to open what I thought was an #ancient
  document (in .tex) - I tripped over a world I was only dimly
  aware of: It's the answer to the question: *Why do all academic,
  scientific papers and PDFs have the same look?" And I found my
  answer: They use something like this instead of Microsoft Word:
  http://www.lyx.org/ I downloaded this beautiful, 2015
  monstrosity: It's not a Word Processor, even though it looks
  like one at first. It can do stuff I didn't know you could
  automate on paper or screen. It also exports to HTML and PDF in
  several different ways, can help you manage bibliographies,
  references, and all that academic / scientific stuff. And the
  fonts they use? Wow... they really are beautiful. I get so used
  to jagged edges (I kinda like jagged edges - I'm always reminded
  of 80s video games when I'm online) - that I forgot what really
  smooth type looks like. Anyway, there you go. I can open my
  ancient document that I snagged from an ftp server that's been
  in operation since at least 1992 - in the ancient days before
  the WWW - that contains a 23 year old code that I'm going to try
  to run in 2015. Why? Because.?
